[MediaWiki-announce] MediaWiki 1.5.5, 1.4.13 released (SECURITY)

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 MediaWiki 1.5.5 and 1.4.13 are a security and bugfix maintenance releases. Detection for uploads of Windows Metafile (.wmf) images has been added to help protect against a client-side vulnerability in unpatched Microsoft Windows operating systems. Sites which have enabled uploads and added non-standard file types (such as .ogg, .doc, or .pdf) should upgrade to this release to ensure that malicious .wmf files can't be uploaded with a fake extension; such files could put visitors to the site at risk. For more details on this, see: http://en.wikipedia.org/wiki/Windows_Metafile_vulnerability Additionally, a maintenance script removeUnusedAccounts.php has been added in 1.5.5; this replaces an older Perl script which had not been updated for the new schema in 1.5.
